It does have kind of a dog whistle tone about it...
I'm not sure which is worse, the small group of people shouting "racist!" or the much larger group of people claiming to be persecuted and projecting. I'm going to reserve my butthurt for those that call out JettaKnight specifically & explicitly. And even so, just because someone wants to make a fool of themselves... well that's on them.
I don't think Jamil was blowing a dog whistle, purposefully, but he did just exclude a sizable amount of people from "Middle America." Goes back to the "can I be American too?" Question I asked a while back, because obviously there are some, regardless of where you are from, who don't consider the sum of America... just those pieces they identify with.
